LOCOMOTIVEGRATE SHAKER.

Specification of Letters Patent.

Patented Aug.. 22, 1916.

Application filed September 16, 1914. Serial No. 862,059.

To all whom t may concern:

Be it known that I, Vieron LnvDs'rnoM, a citizen of the United States, residing at Mus .kogee, in the county of Muskogee and State of Oklahoma, have invented certain new and useful Improvements in Locomotive-Grate Shakers, of which the following is a speer iieation.

An object of my invention is to provide a grate shaker constructed and arranged to be attached to a locomotive and to have the parts thereof mounted in conjunction with moving parts of the locomotive in such relation that the shaker mechanism may be operated upon travel of the locomotive in either' a forward or rear direction to shake and clean the grate.

A further object is to so construct and attach the parts of the mechanism that the structure to be actuated by the locomotive is normally held in an inoperative position and may be brought to the operative relation at the will of the operator.

A still further object is in the provisionl of a structure constructed and mounted to permit variations of thev operation to vary ythe shake of the grate, and to place the above mechanism to be at all times within the control of the operator.

lVith other objects in View, which will be referred to, my invention consists in the peeuliar combination and novel arrangement of parts, such as will be hereinafter more fully described in connection with the accompanying drawings and more particularly pointed out in the appended claims.

1n the drawings: Figure 1 is a view in side elevation of a locomotive with parts thereof illustrated diagrammatically and with my invention schematically shown thereon. Fig. 2 is a view in side elevation of the mechanism of my invention. Fig. 3 is a view in end elevation of the structure vdisclosed in Fig. 2. Fig. 4 is an enlarged fragmentary View to better illustrate the manual control means. Fig. 5 is a fragmentary perspective view of the drive wheel from which the operating power is taken. Fig. 6 is a sectional view through a mechanism which may be adapted to permit manual shaking of the grate.

The grate structure which is only diagrammatically illustrated in Fig. 1 may be of any form and may be mounted to be operated in any desired manner, the one essential feature being that this grate be of shaking type. The several grate members 1 are mounted in any approved manner in the locomotive structure to form the grate upon which the fire is supported. These grate members 1 are of the rocking type and the rocking arms thereof are connected together by a link 2 so that movement transmitted to this link will shake each of the grate members.

A shaft 3 which is preferably one ofthe laxles of the locomotive and is thus constantly driven without thenecessity of intergearing has a drive wheel 4 mounted thereon and this drive wheel 4 is keyed or otherwise secured against turning movement on the shaft.

The supporting frame members 5 are rigidly secured in any desired manner beneath the floor 6 of the cab of the locomotive and a shaft 7 is journaled across one end of this supporting frame and has the cranks 8 and 9 provided thereon, it being preferable that this shaft 7 be positioned on the supporting frame between the disposition of the shaft 3 and the mounting of the grate section. A bracket 10 is mounted to depend from floor 6 of the locomotive and is preferably alined above the shaft 3, and the slide bearings 11 mounted on this bracket 10 which is virtually a portion of the supporting frame 5 have a shaft 12 journaled to be capable of free rotatable movement therein. A power wheel 13 is mounted on the shaft 12 and coil springs 14 are mounted between a portion of the supporting frame 5 and the slide bearings 11 to normally hold these bearings 11 and consequently the wheel 13 in an elevated position.

The drive wheel 4, as better illustrated in Fig. 5, has a friction coating or surface 15 provided around the periphery thereof, and this friction surface might be in the nature of a rubber covering. A belt 1G is mounted over the power wheel 13 and the operating wheel 17 carried by the shaft 7 and any movement which may be transmitted to the wheel 13 will consequently carrythe operating wheel 17 and the shaft 7 will be rotated toward a rotation of the crank arms 8 and 9.

As has been hereinbefore stated, the power wheel 13 is mounted vertically above the drive wheel 4 and with the springs 14 in their normal or unflexed relation, the power wheel 13 will be held at such a position that engagement thereof with the drive wheel 4 through this belt 16 is prevented. However, it is desirable that means be provided to cause a depression of the bearings 11 against the tension of the springs le and to consequently bring the power' wheel 13 and the belt 16 mounted thereon in a bearing relation against the friction surface of the drive wheel i at proper predeterniined intervals and to accomplish this end the bifurcated pressure rod 1S is mounted in bearings provided on the bracket 10 to extend up through the iioor 6 of the locomotive and at its upper free end has a tread 19 provided so that the pressure bar may be engaged by the foot of the operator and by exerting pressure thereon will cause the belt 16 to be engaged against the friction surface 15 of the power wheel 4 and as this power wheel is being rotated in the one direction or the other by the normal operation of the locomotive in a forward or rear direction, motion will be transmitted to the shaft 7 and the crank arms 8 and 9 will be brought .into operation. rThe operating rods 2O and 21 are connected at their one end with the crank arms 8 and 9 and at their free ends have a pivotal connection with the links 2 by which the grate members are rocked or shaken.

The operation of the parts will be as follows: rl`he grate members 1 are moved to a position of proper setting to have the lire built thereon, then as the locomotive is started, turning motion is transmitted to the shaft 3 and the locomotive is operated under normal conditions. When it is desired to clean the grate or shake the fire, pressure is exerted upon the tread 19 and the bearings l1 are borne downwardly against the tene sio-n of the springs 14 thus causing the belt 16 to be brought to bear against the friction surface 15 of the wheel 4 which is constantly rotated during the running of the locomotive, the engagement of this belt 16 causes rotary motion to be carried to the opera-ting wheel 17 and through the turning of this wheel the shaft 7 is rotated thus causing revoluble movement of the crank arms 8 and 9 and through the connectionof the operating rods 21 and 20 with the links 2 by which the grate members 1 are connected accomplishes a shaking of the grate.

ln the disclosure in F ig. 6, a mechanism which may be adapted to permit manual operation and shaking of the grate is illustrated and this structure comprises a case 22 which may be secured to the locomotive structure adjacent the disposition of the grate. 'A cap 23 is provided to close the outer end of the case 22 and a shaker bar 24: is passed through the cap 23 and extended through the case 22 to connect on its inner end with the links 2 by which the grate members are connected, a. shaker handle 25 being pivotally connected at its one end at 26 to the cap 23 and having the outer end of the shaker bar 24 pivotally connected therewith so that as the shaker handle 25 is moved in a swinging path about the pivot 26, the motion transmitted through the shaker bar 24 to the links 2 will cause the grate members 1 to be rocked and a reciprocatory movement transmitted to the handle 25 will be translated in the form of a shaking motion to the grate member 1. V

From the foregoing it will be seen that I have provided a grate shaker which may be arranged with moving parts of a locomotive in such a. relation that motion may be derived at any desired time during the forward or rear travel of the locomotive to cause a rocking of the several members of the grate and a consequent shaking thereof i and further it will be seen that by a variation in the pressure exerted upon the tread 19, the contact with the power wheel 4 may be regulated and in consequence the degree of activity of the shaking mechanism gov erned, also it will be noted that the operation of the mechanism is at all times within the control of the operator.

l/Vhile I have herein shown and described one specific form of my invention, it will be understood that slight changes might be made in the form and arrangement of the several parts of the structure without departing from the spirit and scope of my invention, and hence l do not wish to be limited thereto except for such limitations as the claims may import.

I claim 1. A grate shaker for locomotives comprising in combination with a shaking grate, a drive wheel, a shaft provided with crank arms thereon mounted at a iiXed point with respect to the drivewheel, a connection running from said crank arms to said grate to cause shaking of the same as the shaft is rotated, a belt pulley on said shaft, asecond shaft mounted adjacent to said drive wheel to be capable of adjusting movement with respect thereto, and to be held at all times a substantially uniform distance Vfrom said .first shaft, a belt pulley on said second shaft, a belt mounted over said belt pulleys to establish driving connection between the same, means to normally hold the shaft mounted adjacent to the drive wheel in a relation that the transmission means to the grate is inoperative, and means to move said shaft to a relation to bring the belt to a gripped engagement between the drive wheel and the belt wheel mounted adjacent thereto to cause transmission of movement to Vshake the grate.

2. A grate shaker for locomotives comprising in combination with a shaking grate, a drive wheel, mounted in conjunction with a rotating part of the locomotive, a shaft adjustably mounted adjacent to said drive wheel capable of movement in a line radially Copies of this patent may be obtained for ual movement of the first mentioned shaft to engage the belt between the power wheel and the drive wheel to cause turning of the power wheel and to consequently transmit movement through. Ithe belt to the operating wheel to cause shaking of the grate.

In testimony whereof I al'lix my si gnature in presence of two witnesses.
